CHARLTON — The Charlton manufacturer Endovision, Inc. will have to pay $27,464 in fines and compliance fees for failing to comply with environmental regulations after an expansion of the facility, according to the Massachusetts Department of Environmental Protection.

"MassDEP observed several hazardous waste and air quality violations during an inspection of the Charlton facility on January 28, 2013 and during record reviews," said MassDEP in a release. "The company has now taken corrective action on all violations and has applied for an air quality plan approval, as required by state regulation."

The violations included failing to obtain an air quality permit to emit volatile organic compounds and hazardous air pollutants and improper hazardous waste container-labeling, management and storage practices, according to MassDEP.

“As the business grew, so did its air emissions and hazardous waste generation, but the company did not take care to address corresponding regulatory requirements,” said Lee Dillard Adams, director of MassDEP’s Central Regional Office in Worcester. “Materials tracking and record keeping systems now in place will help the company comply with environmental regulations and result in significant savings.”

MassDEP is responsible for ensuring clean air and water, safe management and recycling of solid and hazardous wastes, timely cleanup of hazardous waste sites and spills and the preservation of wetlands and coastal resources.
